Pin Position?

What is Pin Position?

All bowling balls have different pin distances out from the CG and various top weights. Usually your pro shop professional will decide what specifics he wants based on your span, relative to where he wants to place the pin and cg and if he wants to use a balance hole. These specifics aren’t necessary for the consumers to choose, but we allow you to pick what you want and we fill all orders exact or as close as possible based on availability.

Pin Position – The pin distance describes how far the pin and the cg are apart. A pin-in ball is where the pin and cg are any where from 0-1” apart. A pin-out ball is where the pin and cg are any where from 1” + apart.

Example #1: Balls with a 0-1” pin will get the ball into a slightly earlier roll with slightly less flare potential.

Example #2: Balls with a 3-4” pin out will give the ball slightly more length and more flare potential than the ball in example 1.

Top Weight?

What is Top Weight?

Top Weight – The amount of imbalance placed in the bowling ball to offset the removal of weight from the gripping holes. Average top weight ranges from 2-4 oz.

Example #1: Balls with 2 oz or less top weight will get the ball into a slightly earlier roll.

Example #2 Balls with 2 oz or more top weight will give the ball slightly more length than the ball in example 1.

Surface Adjustment?

This feature allows you to choose a different Abralon finish on your new ball. You can choose 500, 1000, 2000, 3000, and 4000 grit Abralon and this will be done by the Storm Surface Factory Machine we have in Connecticut. By choosing this option, your order can be delayed if we do not have specs requested on the premises.

IF THEY KNEW WHAT WAS COMING, THEY’D NEVER SLEEP.
From out of the shadows, I emerge as the winner. The moment I hit the lane, I dominate my foes and leave them agonizing over what’s coming next. My all-new Cage™ Core is the nucleus from which my rage builds, leaving my competition contemplating their exit strategy. They can either bow out now, or leave with their heads in their hands.

COLD, CALCULATED ASSASSIN.
What my competition can’t see is that I’ve taken every step to ensure their defeat before I even arrive. My newly designed Cage™ Core is a premeditated plot to produce superior midlane motion without sacrificing down lane continuation. Did they think they had a chance?

A MENACING COMBINATION.
I lie in wait, ready to ambush my rivals with a wicked one-two blow. The pearl portion of my 76H™ Hybrid Reactive Coverstock eases through the front end while the solid part provides sure-fire continuation through the breakpoint — allowing me to push my opponents past their breaking points.

CONSPIRE TO BE VERSATILE.
I was created to devour heavy oil, but with my 4000-grit Pad finish, my scheme is to adjust my rough exterior to also combat medium to lighter conditions.
